Do you think these would make a good E-fan setup?

2 16" fans

2 DCcontrol controllers (redundency)

2 led indacators (1 per fan)

 

HI!... I highly recommend the DERALE electric fans. I've been running two of their 16 inch fans for over 7 years now with no problems. At the time I bought mine, I got them from SUMMIT RACING for $95.00(U.S) each, plus another $45.00(U.S) for the PERMA-COOL electronic thermal controller. Now I just run the two fans with manual switches to turm them on and off. Rarely even use the fans at all due to my truck runs so cool. I believe the DERALE fans now go for about $120.00(U.S) each.

 

Neal, how do you have those things mounted? From what I can tell it looks like you used the plastic push through zip tie mounts that most people seem to be afraid of. How long have those fans been mounted like that? Have you had any problems with them rubbing through the core? I used them on my '98 4.2, but they were only there for about a year or so before I traded it in so I have no idea how well they've held up.

 

I have mine mounted the same way, no issues at all, 20k miles

 

I like the permacool fans 'cause they only draw 11 amps.
does any one else know if the controller is any good or not?

 

HI!... I have not had a problem at all with the plastic mounts. The copper rods that originally came with the fans wore through my rad in a year. Last 6 years with the plastic ones have had no issues.

 

I like this better. Better mounting, a built-in shroud, includes a variable controller and provides a place to mount your intercooler reservoir if you decide to SC.

 

What is the advantage of e-fans over the stock fans? Sorry about the newb question but I never realized all the mods that are out there for pick-up trucks.

 

From the Flex-a-lite web site:

"An electric engine-cooling fan built for the demands of your big truck, and then some. This fan -the most powerful on the market- is the answer to the overheating problems caused by slow in-city driving or heavy towing, and solves the cooling problems that occur with body lifts. This unit responds based on cooling need (not just engine speed) to maintain optimum engine temperature. Up to 17 additional horsepower -dyno proven- is transferred to the wheels by removing the belt driven fan and fan clutch. Decreased load on the engine results in improved fuel economy - up to 2-3 mpg. Pulls a whopping 5,500 cfm."

 

what about a 180 degree T-stat?

 

I don't own one yet, everything I know came from there web site. But, the temperature when the fan comes on is adjustable, if that is what you mean.

 

Also, the main advantage is reducing what is known as parasitic loss. This is similar to running under-drive pulleys that reduce the load on your engine. Normally you have a mechanical fan that is attached to the output shaft of your water pump that drives your fan clutch and the fan that draws air through your radiator. By removing the 5 to 10 pounds of reciprocating weight, your engine is able to spin up faster with less drag from having to turn the mechanical mass. This will give you better gas mileage, quicker throttle response and more power to the rear wheels. They also don't apply an extra load to you water pump that may increase the life expectancy of the bearings within the pump. As far as increasing HP, I don't agree with a 17 HP increase though, I think, maybe a 5 or so HP gain may be realized. In my experience, mechanical fans are more reliable and you can always brag that you have a 300 HP fan.

 

Thanks Neal. Exactly the kind of info I was hoping to hear. I've been struggling trying to figure out some alternative method to mount my fans and have yet to come up with something that would be effective and not be too costly.

MeanGene, I agree mostly with what you said, but I think the hp gain is probably going to be a little more. I'm going to say it's probably closer to 10hp. You also have to take into consideration the drag just from the fan turning and having to move the air along with all the points you mentioned.

 

HI!... There are many guys on here who have shown increases of 17-19H.P on the dyno after installing electric fans. I have personally seen it.

 

im one of them!
